This book was released on 2013-12-21 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supercritical Fluid Technology for Energy and Environmental Applications covers the fundamental principles involved in the preparation and characterization of supercritical fluids (SCFs) used in the energy production and other environmental applications. Energy production from diversified resources — including renewable materials — using clean processes can be accomplished using technologies like SCFs. This book is focused on critical issues scientists and engineers face in applying SCFs to energy production and environmental protection, the innovative solutions they have found, and the challenges they need to overcome. The book also covers the basics of sub- and supercritical fluids, like the thermodynamics of phase and chemical equilibria, mathematical modeling, and process calculations. A supercritical fluid is any substance at a temperature and pressure above its critical point where distinct liquid and gas phases do not exist. At this state the compound demonstrates unique properties, which can be "fine-tuned," making them suitable as organic solvents in a range of industrial and laboratory processes. This volume enables readers to select the most appropriate medium for a specific situation. It helps instructors prepare course material for graduate and postgraduate courses in the area of chemistry, chemical engineering, and environmental engineering. And it helps professional engineers learn supercritical fluid-based technologies and use them in solving the increasingly challenging environmental issues. Relates theory, chemical characteristics, and properties of the particular supercritical fluid to its various applications Covers the fundamentals of supercritical fluids, like thermodynamics of phase and chemical equilibria, mathematical modeling, and process calculations Includes the most recent applications of supercritical fluids, including energy generation, materials synthesis, and environmental protection

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Plastic materials have experienced a spectacular rate of growth in recent decades, consequently, production of plastics, and likewise their consumption, has increased markedly since 1950. Moreover, they are lightweight and durable, as well as can be moulded into a variety of products that can be manufactured in many different types of plastic and in a wide range of applications. Inevitably, continually increasing amounts of used plastic are originating daily, resulting in a plastic waste problem. The final objective of this research is to achieve a good overview of currently plastic waste situation in order to propose several improvement strategies for favouring the reduction and utilization of this type of waste. Definitely, contribute to sustainable development and protection of natural resources through proposals of recovery and reduction of plastic waste disposed in landfills. In order to improve the reduction and recovery rates of plastic waste, it is important to implement the 4Rs strategy in waste management, or waste hierarchy, a sequence of actions in the order of decreasing environmental desirability, including reduce, reuse, recycle materials and recover energy, with prevention as the most favoured option and disposal in a landfill as the least desirable management strategy. For this reason, many measures in order to reduce the volume of plastic waste generation are proposed, that is, actions to be implemented before product end-of-life, during pre-consumption and consumption. Finally, some proposals to increase the utilization of recovered plastic and to improve plastic waste treatments are proposed, that is, actions to be implemented after product end-of-life or post-consumption. In addition to this, current applications of recycled plastic waste and future research are reported.

Download or read book Feedstock Recycling of Plastic Wastes written by Jose Aguado and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of plastic materials has seen a massive increase in recent years, and generation of plastic wastes has grown proportionately. Recycling of these wastes to reduce landfill disposal is problematic due to the wide variation in properties and chemical composition among the different types of plastics. Feedstock recycling is one of the alternatives available for consideration, and Feedstock Recycling of Plastic Wastes looks at the conversion of plastic wastes into valuable chemicals useful as fuels or raw materials. Looking at both scientific and technical aspects of the recycling developments, this book describes the alternatives available. Areas include chemical depolymerization, thermal processes, oxidation and hydrogenation. Besides conventional treatments, new technological approaches for the degradation of plastics, such as conversion under supercritical conditions and coprocessing with coal are discussed. This book is essential reading for those involved in plastic recycling, whether from an academic or industrial perspective. Consultants and government agencies will also find it immensely useful.
